Clamping connection reinforcing method for assembly type concrete hole hollow slab bridge
The invention relates to a clamping and reinforcing method for an assembly type concrete hole hollow slab bridge. The method comprises the following steps that: 1, the span x of the hollow slab bridgeis measured, a steel cross beam, made of H-shaped steel, with a proper section is selected, and the shear stiffness of the steel cross beam is determined according to a steel cross beam shear stiffness curve formula; 2, the steel cross beams are placed on the lower surfaces of the hollow slab beams forming the hollow slab bridge, every two adjacent hollow slab beams are hinge joints, opposite-pull screws are arranged in the hinge joints in a penetrating mode, the lower ends of the opposite-pull screws are fixedly connected with the steel cross beams, and the upper ends of the opposite-pull screws are connected with an upper steel plate; and thirdly, a fixed connection material is poured into the hinge joint at the position where the opposite-pull screw is arranged, and a connecting deviceis fixedly arranged at the end of the steel cross beam and used for fixedly connecting the upper steel plate with the steel cross beam. The method has the effect that the hollow slab beam reinforcingperformance of the steel cross beam is better.
本发明涉及一种装配式混凝土孔空心板桥的夹联加固方法，其包括如下步骤，步骤一，测量空心板桥的跨径x；选择合适截面的钢横梁，钢横梁为工型钢制成，先依据钢横梁抗剪切刚度曲线公式确定钢横梁抗剪切刚度；步骤二，将钢横梁放置到形成空心板桥的空心板梁下表面，相邻的两个空心板梁为铰缝，铰缝内穿设对拉螺杆，对拉螺杆的下端与钢横梁固定连接，对拉螺杆的上端连接有上钢板；步骤三，在设置对拉螺杆的位置处的铰缝内浇注固接材料，在钢横梁端部固定设置有连接装置，连接装置用于将上钢板和钢横梁固定连接。本发明具有使钢横梁对空心板梁加固性能更好的效果。
